BIOS: HOL_723.ROM Incorrect

While I agree WIN 10 should not have been said, your being somewhat harsh with OG. We all have our bad days.

I seem to have them more frequently being subjected to browser choices. Alas, I wandered off ?

What is very relevant is the original WIN 7 BIOS that was installed, (your machine was shipped with a non-UEFIvBIOS), and the fault lies with you. Your trying to re-install the same BIOS version and SSID.

HP has the SNAFU, not the OP. In sincerity, and without offense, one has sidetracked the issue at hand with bogus responses. I am not a neophyte...I recently built another desktop computer using a "new" and identical motherboard, which includes the OEM BIOS/UEFI, and it too could not be flashed.

BIOS: HOL_723.ROM Incorrect

As the motherboard of the p6-2133w is a NOT a UEFIvBIOS board, it would fail. You can not flash a UEFIvBIOS onto the

Hibiscus motherboard shown here, as it does NOT support that action.

As your unwilling to understand this issue, I wish you the best. I shall not comment further, as I am a volunteer. Your asking for advice on a system (circa Jan 2012) that is OUT of warranty. Thus HP should not have any interaction with you.

@84B23F, I guess I certainly started a Fire-storm. I appologize for the incorrect information that I posted previously. I had two pages open in my browser for two different computers and looked at the one that had Win 10 installed. This lead to my incorrect post.

Now, the only explanation that I can come up with for your problem is, HP uses their motherboards in several different models of computers. They sometimes list BIOS updates for the other motherboards in the specifications (confusing!!). In your case, I am not certain that the BIOS update is for your motherboard. I can't find any information that shows your motherboard as being from the ROM Family 2ACF. This is normally in the Motherboard Specifications.

3. sp69356.exe - This is HP's exe file to be execuated, and it is found at C:\SWSETUP when done. It contains drivers/pdfs, but most people would not be aware of its content. Nothing happens when upgrading BIOS/UEFI.

4. BIOS/UEFI - This may have been a first generation...I have two motherboards, one with 7.16, and one with an earlier version. I know version 7.07 existed. And in that post, it was indicated "Pegatron 2ACD Motherboard," which further suggests on HP's web site that ROM Family 2ACF is incorrect for this motherboard.

I haven't downloaded this updated utility. But, with safuwin.exe, I copied UEFI BIOS from one motherboard, and could not install it on another motherboard....both boards are identical. I thought about resetting the CMOS, and then try, and also thought about trying at DOS level...no Win7 running. Just ain't got the time now to fiddle.

6. d:\Flash>safuwin /clnevnlog - When I run this command in a DOS window, both motherboards get this result, "System BIOS image invalid or corrupt." Clnevnlog switch is suppose to "Clear Event Log" So, safuwin.exe may or may not be the correct flash program.
